Over at Slate, tech writer Michael Agger highlights a few Google Labs features aiming to save us from our email mistakes. We've covered them all before, but as a refresher, you should check out previously mentioned Labs features like the Forgotten Attachment Detector, Mail Goggles, and Undo Send—all very cool Gmail additions we can employ in the fight against silly, preventable email mistakes.

NPR saw the Slate article and thought it'd be fun to hear their listener's worst email blunders, and we can't help but agree, so why don't you share your worst email gaffe—and whether or not any of these Gmail Labs features could have helped you out—in the comments.
